Question

Area of four walls is also called as:

Answer 1

Hey Mate!!!

This is the answer

Formula of the area of four walls,

=> (area of the base ) + (area of ceiling)

=> Area of base = l * b

=> Area of ceiling = l * b

So,

=> (area of the base ) + (area of ceiling) = 2(l*b)

=> As per Surface area of a cuboid we have 2(l+b)*h

Then finally we get,

Area of four walls = 2(l+b)*h

Hope it helps..
